Upgrade your exhaust system with these 304 Stainless Steel Exhaust Headers, designed for select 2002–2013 Chevrolet, GMC, and Cadillac trucks and SUVs equipped with LS-based 4.8L, 5.3L, 6.0L, or 6.2L V8 engines. Featuring 1-5/8-inch mandrel-bent primary tubes and 3/8-inch-thick flanges, these headers provide a durable replacement for compatible factory exhaust manifolds.
The passenger-side outlet features a beveled ball-and-socket flange designed to connect with compatible factory-style Y-pipes that use a matching beveled flange and donut-style gasket. This connection design supports proper alignment and exhaust sealing when the mating components are compatible.
Constructed from 304 stainless steel, the headers offer heat resistance and corrosion protection. Precision-welded construction and included multi-layer steel (MLS) header gaskets provide a robust installation setup for compatible applications.
Designed for direct bolt-on installation on vehicles with matching factory exhaust configurations, these headers are intended to replace the original manifolds without custom fabrication. Verify the passenger-side Y-pipe flange type before ordering, as compatibility depends on the original exhaust connection.
